We build our own AI products.
Then we build yours.
Next Combinator is a product studio in Dhaka. We design, ship, and operate our own AI platforms — voice agents, generative media, marketing automation — and bring that same engineering to client work.
What We Ship
These are our platforms — designed, built, and operated by our own team. The engineering behind them is the engineering we bring to client work.
HelloKit
Replace stiff IVR menus with fluid, conversational agents that handle scheduling, support, and sales calls with <500ms latency.
Marketing Kit
End-to-end autonomous marketing for Meta. Our agents generate high-conversion creatives and optimize budget 24/7.
Pixigen AI
The all-in-one generative media studio. Create hyper-realistic images, studio-quality voiceovers, and marketing videos from text.
OpusCall.ai
A 24/7 AI receptionist for businesses where a missed call is lost revenue. It answers, books the appointment straight into the calendar, qualifies the lead, and sends the confirmation — then hands you the transcript.
Google, Outlook, Apple, and Calendly.
Plus 14 industry-specific templates.
Canadian-hosted data residency.
All in, cancel any time.
The Same Engineering, Applied to Your Product
Running our own platforms means we maintain what we ship — so we build client systems the way we build our own: to survive contact with real users.
Custom AI Agents
The conversational agent stack behind HelloKit, adapted to your domain — agents that handle scheduling, support, and sales calls, not demo scripts.
Enterprise SaaS Development
Multi-tenant platforms on Next.js, TypeScript, and Python — authentication, billing, and analytics wired up properly, so you can add customers without re-architecting.
RAG & Semantic Search
Turn your internal documents into something your team can actually ask questions of. Vector search and embeddings, tuned so the answers cite real sources.
Workflow Automation
Workflow automation for the processes that don't fit off-the-shelf tools. We map how your business actually runs, then build to it.
How We Deliver

Discovery & Strategy
